Application tiled August 16, 1917. Serial No. 186,617.

To all 'whom t may concern.'

Be it known that I, MYRoN M. METZINGER, a citizen of the United Statesof America, residing at Blair, in the county of Washington and State ofNebraska, have invented certain `new and useful Improvements inConcrete-Block Wall Structures, of which the following is aspecification.

My invention relates to improvements in i closure, or standardized sizesof curved or circular walls for round inclosures.

Second, to supply a simple and effectual mortar bond for t'he bed andhczu'ling'joints of all general work with means adaptable and easilyadded for special requirements.

Third, to provide metal reinforcement of each unit or block and meansfor continuously connecting all thc units of reinforcement and blocks ina course of wall work, as well as to connect thc different superimposedcourses of blocks and reinforcements in a wall, and,

Fourth, to facilitate the exclusion of inwardly penetrating moisturethrough the completed wall structure, as well as the thorough drying outof newly erected structures, and thereby avoid special exterior coatingson the completed structures.

I attain these objects by thc structural elements -illustrated in theaccompanying drawings in which- FigureI 1 is a fragmental j'wrspcctiveview of a building corner made of such a wall structure, showing the topand outside face of a portion of wall thlce courses high; Fig. 9 avertical crosssect.ion of such a wall, taken on the broken line 2---2 ofFig. l; Fig. 3, a like section, taken on the broken line f'm-' of Fig,l', Fig. 1., a top or plan view of n course of blocks arranged toproperly bond as the next course in height on the wall as shown in Fig.l; Fig. 5, a perspective view of the regular outside stretcher blocksfor straight walls; Fig. o, a perspective view of thc outside angle orcorner block for each cour-sc; Fig. i', a perspective view of the closerblock for one side of an inside corner of every course; Fig. 8, is afragment of a plan of curved wall, such as is used for silos and grainbins; Fig. 9, an enlarged plan of a curved wall stretcher block,disclosing the manner of metal reinforcement; Fig. 1t), a plan of aregular corner block, with its embedded reinforcing strip of sheet-metalcorrectly placed, Fig. l1, a perspective view of a bcnt end portion ofthe Hat bar or sheetinetal block-reinforcing strip and the verticalconnecting or locking rod; Fig. 12, an enlarged perspective view of thesmaller end of an outside. corner block; and Fig. 13, is an enlargedvertical section of a small block fragment, taken through one of thehernisphcrical mortar dowel pits. In all of these views similarreference numerals indicate similar parts of the structure.

Aside from such cut. blocks and closers as may be required to fit aroundwall openings and for adjusting lengths of walls. there are onlythrec'shaj'ies of blocks in this general structure; these arc shown inFigs. 5, and 7, and are of shapeI described as follows:

The stretchers for regular straight walls, lboth inside and outsidefaces, are of the same U-shapc, consisting of the straight body part 4f,having at its ends the rightai'igularly-disposed cross-bonding legs 5and 5. For curved walls, silo or gram-bin structures, these stretchersarc modified only by curving the body portions i to correctly line theouter and inner wall faces as required, and adjusting the lengths of thebodies to bring the inncr and outer bonding legs 5 to coincidelongitudinally for correct radial or cross bond, as shown in Fig. 8.

The outside corner blocks of a course each consist of an L-shaped bodycomprising a base limb 7 of length equal to the regular wall stretchcrsand a branch limb of onehalf that length. The projecting end of cachlimb is provided with an inwardly` standing bondingdcg 8 to coincidewith and be disposed between the bonding legs 1() and plain ends 11 ofthe adjoining closcrs in adjacent, subjaccnt and su )eriniposedcourses,-see Figs. l and 4. These corner blocks are inverted, andreversed in position, for cach successively imposed course of blocks inthe wall.

The inside corner closers or blocks are t, having on one end only theangular outwardl)` standing cross-bonding leg l0; the, opposite plainend 11 being of sutiieient length to lap and bond with the bonding legs8 on the short limbs t3 of the outside eorner blocks of the adjacentcourses above and below.

The hemispherical dowel pits 12 are madel in both bedding faees of allthe blocks, disposed directly opposite. on opposite faces of the bloeit,so as to registerI and stand opposed in all opposed bleek faces on thesame mortar bed or joint. To attain this agreenient of position of pitsin the opposed hedding faces fo the blorlts in the 'all, thelongitudinal rows of pits are disposed centrally of the bed faces of thebodies of the blocks amb-the cross rows eentrally of the bed fares ofthe emes-bonding legs; widths,l of legs and bodies being made equal andthe pits coinposing eat-li pair of pits spared equally lengthwise oleaeb leg and at the renter of the length of eaeh body part: and the pairof pits at. the longitudinal center ot' eaeh body bed register with theend or angle pits of the interbonding sltbjaeent and imposed stretel-ierblot-lts. It will be observetL by' noting Figs. 1 and l, that thisarrangement disposes the pits` in pairs of cross-rows in the wall. apair of eross ronvs at eat-h plaeeof eross-lnmding; also giving threelongitudi nal rowsl of pits in the wall; the ventral one of which beingkept in longitudinal aline ment eontrols the thickness of wall as wellas the width of the hollow betaveen inner and outer fare blo'slts.These. pits heilig earetally lille/tl with a strong'naa'tar form an anrhoring ball.. as illustrated at 1'. in l `igs.-3 and lil, that for anyordinary requirement prevents any possible lateral or horizontal shiftof super-imposed blocks or courses of bloelts ,in a` wall.

A further advantage of the above disposition of these bonding pits willbe apparent. in the reinforeed blocks and inereased botuling meanscombined therewith for walls where greater resistance to very heavystrains are requiredf-ivhieh is set forth as follows: The. perforatereinforcing strips 16 are made of flat bar iron or heavy sheetmetal.eorners and to forni the bonding-leg reinfori-ing longues or legs 2Lartl made b v bending the metal strip ohliquely llatwise upon itself asshown in Fig. 1l., When this metal reinforeement is bedded in the renteror core of the bloeks,as disclosed in lligs. 2, 3, S.) and 10, and thehloek has become induratedv` these angles are quite as rigid and strongas if stamped integrally angular from the sheet; metal. As shown in Fig.J the intermediate body portion lll is stamped out with the, requirededgewise'curvature and the leg angles made as in other eases.

All of the-se reinforcing strips have the -lonall the required positionsotA 'llho angles 18 to shape around the gitudinal rows of perte-rations1T, as soon n. to give. the` strip a, more seeurtbed in the bleek. andte reduee to the minimum separa tion or division of the bloeit by thestrip. The terminal or outer end perforation-- li" at the outer ends ofthe reinforcement legs` 21, are of size and are set coincident with andform part of the walls of the dowel pits 19 ir the bonding legsA Thesedowel pits extend vertu-ally elear through the legs and those insuperimpostal eourses register with each other. as shown in l'" v Ji,Vertical bonding or dowel rods 3;. as shown in Fig, ll, of smallerdiametri' to he flushed in around by mortar, may be seated in theserontinuous rertieal pits; or iwheri` the maximum oly strength and bondare required, riuso-fitting reriieal doive! rods are. seated therein.Matting this veitieal dowel--rml eontinuons. l have a strut-,turereinforced and bonded against ail the .strains to which .etrueturalwalls are subjtrted.

lhe V-shaped vertieal grooves 2U. are diS- posed in the endsy ofthebioelts and set; nearest to the fare thereof. ln the walls thev forni.square vertieal wells don a through the heading joint. see Figs. l andl., of snllieient size to readily tal; i a illing ol' mortar. Thisfarilitates full flushing ofthe heading joints :with mortar and forms aheading joint look. preventing an); possible lateral movement of eithe`adjoining bloeit. lt serves as an anehorage for any rake-out, pointingof the lfathng joints and faeilitates attaining a heading joint that isair and watier tight:

In walls` laid of bloeks proportioned in sizes as shown. there are thelarge flue hollows 14. vertieally rontinuous` and the spaces between thereeurring eross-bonding legs. The inwardly extended ends of the legs areall spared a way from the, backs of the opposite. bleek bodies. to fornithe narrow eonlmunieating slits 13 between the fines. By this means thenew wall is easily dried. by leaving external openings at top and bottomof the wall hollow. To further render the wall impervious or weatherproof, the entire inside surfaee of the body and bonding legs oftheoutside wall blocks` have a water proof eoatingtor layer 15.r Thiscoupled with the use of a waterproof mortar in which the blocks arellaid excludes all weather moisture or dalnpnees from the inner face ofthe wall-`r and avoids the neces sity of any exterior wall treatment.that would mar the color or natural texture of the outer wall surface.

I claim:

1'. A conerete-bloek wall-strueture, comrisiug opposite faee walls' oflike blocks aterally spaced to form a. hollow wall. inwardly projectinglegs on the backs of the bloeks to interlap with the legs of bloc-ks ineourses below and above of the opposite, fare wall to bond the fanowalls across the holmesses low,v reinforcing bars, disposed lengthwiseIof the Wall inthe bodies of the blocks, integral legs on thereinforcing bars standing angularly therefrom and disposed into the legsof the blocks and having. terminal eyes therein, and a centrallongitudinal row of vertical locking rods disposed through saidinterlappingblock legs and terminal eyes. 2.
